AWNING FIXTURE Patented June 9, 1931 JOHN W. SHAW, or NoRwoon,

AWNING FIXTURE Application filed May 24,

My present invention is concerned primarily with awnings, moreespecially with those of the spring roller type, and relatesparticularly to operating means therefor by which the awning may beadjusted from the inside of 'a room without opening the window.

An object of the invention is to provide adevice of the character notedabove, which is may be "interchangeably used'with various types ofspring roller awnings and which is universally applicable to a widerange of window sizes and window styles, both of the drop sash and ofthe fixed sash types of window. x v

The usual spring roller awnings embody in the rollers a ratchetmechanism which is more or less flimsy, and (which is so exposed to theweather that it may quickly become rusty and ineffective. In consequencewhen the awning, 'in partiallyor fully lowered position is blown aboutby the wind, this ratchet mechanism is sometimes released or broken, andthe awning rolls up with a snap and abang,-frequently damaging both theawning and its supporting fixtures and making a most disconcertingnoise. V It is accordingly an object of the invention to provide anawning operating means of the above type, in which the flapping orundesired release of the holding mechanism is recluded and whichmechanism jyet reac ily responds to the usual manual opera tion to raiseor lowerthe awning.

Another object is to provide a substantially fool proof operatingmechanism adapted to withstand hard usage and so designed that itscarelessmanipulation cannot 40 result in damage to either the awning orthe operating gear. 7 7

According to my invention the operating tape is provided with anautomatic check arranged in protected position out of' the weather,preferablywithin the room, and

which may serve either to supplement the roller ratchet mechanism or asa substitute therefor. j

The check normally prevents spring-roller urged movement of thetape. A;slight man- 1925. Serial in). 280,150.

however, 'suflices to disengage it from the check so that it may runfreely outward as thespringroller winds up the awning.

The tape passes over guides on bracket fixtures arranged adjacent thetop ofthe sash and on opposite sides thereof, oneof these fixture'sialsocarrying the tape check. These brackets are preferably each made ofapair of relatively slidable parts so that they may be arranged to fitany-standard type of sash throughwhich the tape. is to be guided. IAnother objectis to provide a mechanism withwhich the above notedadvantages are had without sacrificing any of the merig toriou'sfeatures and noteworthy advantages of the .awnlng'operatlng meansdisclosed in myprior application Serial No. 171088. filed presentinvention Feb. 26, 1927, on which the is an improvement.

Other objects of the invention are to videa mechanism-ofsiinplepractical construction which maybe conveniently? {attached to a window,which willbe rugged,

durable and efficient in'use and which is Well suited to therequirements of economical manufacture.

VVlth the above noted and other. objects in View, the invention consistsin certain novel features of construction and combina tions andarrangements of parts which will be more fully hereinafter described andc pointed outin the claims. c The invention may be more fully understoodfrom the following description in connection with the accompanyingdrawings wherein: Y

c Fig. 1 is a perspective view showing the outside of a window equippedwith an awn- 1 ing (shown partly lowered). and adapted to be operated bythe mechanism of the present inventioni r 1 i v Fig. 2 is a view on a.larger scale in vertical section taken approximately on the line. 22 ofFig. 1." r

Fig. 3. is asectional plan view taken ap-. proximately on the staggeredline 3----3 of Fig.2..

Fig. 4 is a vertical sectional detail taken.

approximatelyon the line of. Fig. 2.

' Fig. 5 is a vertical sectional view onthe line 55 of Fig. 3. v

Fig. 6 is a View similar'to Fig. 2 but showing the operating-mechanismapplied to anothertype 0f. sash and showing the. operating flexible'devicedrawn to a posiends of the roller being mounted in conventionalhangar brackets 15, 16 secured to the 7 top of .the window frame 10exteriorly of the sash 11, the latter bracket having the usual slot forthe fiat gudgeon.

fA cross bar passingthrough ahem 18 near the free end of the awningisformed Y integral with a pair of arms 19, the ends ciated crossbartends to unroll the awning 'of which are pivoted to brackets 20 securedY to the uprights of the window frame'lO,

The. Weight of the arms 19 and their assowhile the coiled torsionalspring 2l'secured within the roller 12 tends to roll up the awning. Thisspring is strong enough to normally overcome the welght of the arms andcross bar; In order to lower the awning, -a -positive unwinding torquemust be applied to the roller. and suitable ratchet mechanism 48 servesto block the; rewinding action of the spring 21. As islthe commonpractice the spring21 is wound about the usual metal core 46 to the hub47 of the flat 0 gudgeon 14. V

The means for unwinding the awning 17 against the actionof the spring 21includes the usual-flexible device 32 preferably in the nature of,atape, one end of which is rolled about the roller 12 between theconvolutions of the awning andanchored with theetlges of the awning totheroller by the anchoring.

" notch 33.

' The mechanism thus far described taken byitself is not my invention,the latter being more particularly concerned with the provisionof thetape checking mechanism for positively preventing inadvertent springwinding of the awning and the construction of the brackets 6 0 and 7 Owhich renders them. universally adjustable. i

The fiexibletape 32 passes through'a slot 7 137 at the upper edge of thewindow pane shown of the fixed sash type and'depends intorthe'roomterminating in a handle loop 7 g Arranged at the outside and inside ofthe sash are tape guiding brackets 60 and the details of'which'will belater described.

These brackets mount rollers such as. the

' portion 28.

rollers 35, '36 of the outer bracket and the roller 38 of the innerbracket for guiding the tape. The inner bracket also carries my improvedchecking means which will be more fully described.

The brackets 60 'and70-may be generally similar to'those disclosed in mycopending application above identified in that they include attachingportions 22 and 27 respec 'tively and flanged channel forming portions24- and 30 respectively. within which the guide rollers are mounted.These channel portions are disposed closely adjacent the window pane andfacing each other at opposite sides of the sash.

- An improvement. over myf prior disclosure however is the manner inwhich the brackets 60 and 70 are rendered universally adjust- V able tolit-various sizes and "styles of windows; The channel portion 24 of thebracket 60 is'adjustabl'e along vertical slot 26 in the depending plateportion 23, this adjustment being'eifected by headedscrews V g 25'working through the slot and engaging the channel piece. Asimilaradjustment of the channel piece 31 maybe effected by adjusting screwsprovided in channel piece 30 to work through slot 29 in the coacting Thepresent brackets are also similar to those disclosed in my copending.applicationin that both brackets are provided with tape guide rollers36'and38 near their tops which guide the travel of the tape through theslot 37 in the window pane. Also the channel piece 24 is preferably ofgreater length than the channel piecev30 and'mounts a guide roller 35well below: the plane of the; upper rollers 36, 38. Thus as the tape 32from. the roller 12 is led through the openingv 34 in the back of thechannel'24 and passed around under theroller. 35 a down pull is exertedon the spring'roller 12 which is thus effectively 1 prevented fromjumping out of its brackets.

.VVhile the adjustable nature of the bracket fixtures herein illustratedis desirablefor renderingthem universally applicable to several stylesof sashes,-it is obviously within the scope of the invention to makesuch brackets as integral one piece stampingsor castings when turned outin large quantities for standard size windows. 7

1 The tape checking means is arranged withthe guide roller 38 This meansmay include a knurled ecce'ntric39 hanging freely on a pivot pin 40connecting the flanges of the channel" 30. This eccentric is 'prefer-,

ably provided with a spur 49 near its lower,

end. The bail 41' pendent from the member 30 is preferably provided witha heavyroller 42 on its crossbar. Thisbail normallytendstomovethe'handle end of the tape 32 to ,a position closely adjacent the in thechannel 30 of the bracket70 below 1 neoaaaa window pane andito hold. thetape in. fric; tional' engagement \Yithpthe. eccentric; '39. The tapeis. led around the roller 3'8 between the eccentric 391 and the backgofjthe channel 30 and thencaforwardly through the bail 41. v

eccentric sihcethe tape, is always moved into engagement with said spurbytheaction of the roller 42in its inward! swing toward the window'pane.

'YVhen it is desired to permit the, spring roller to wind. uptheuawning, the endzof the tape is grasped and drawn rearward ordownward, thereby swinging the roller. 43

well rearwardl'y and. disengaging the tape from the spur 49 of theeccentric 39. As long as the inner end of the tape is manually held fromreturning to the position of. Eig. 2,, the tape may run. freely in anoutward direction without any interference; from the eccentric,

It may be noted that the action of the eccentric and its associated tapeengagingmechanism is. entirely independent of the usual pawl, andratchet. mechanism of! the roller and is much morepositive in operationthan such mechanism. The tape engaging means dispenses with the need forconven' tional' ratchet and pawl mechanism and the simplified springroller of Fig. 7 devoid of ratchet mechanism may be conveniently used.The parts of 7 bear the same reference numerals as the correspondingparts of Fig. 8'. 7

Even though. the awning is in fully or partially lowered position and isbeing blown about by the wind" in a manner in which would render theordinary ratchet and pawl mechanism of the roller inefi ec tive, thereis no. danger of theeccentr-ic tape retarding means failing to function,and there is no danger of the-spring roller being gentially to theroller.

released to wind; up the, awning with an undue rapidity which mightinjure the mechanism.

InFig. 2 it will phenoted-that the channel members 24, 30 are disposedas closely as possible to the window pane and that their upper. edgesabut the lower face of the upper-cross bar 50 of the fixed sash 11. InFig.6, however, the channel pieces 24 and 30 are so adjustedv that theyabut the win dow framelO immediately adjacent the in ner and outer facesof the upper cross bar 51 of a sliding sash. Here the tape passesthrough a notch 52in the top of the cross bar 51 so-that it willnotinterfere with the usual raising and, lowering ofthe sliding sash. tapeand the awning. 'As a consequence,

In Fig. 6 Ihave also shown a slight modificationin that the bracketplate28isshortenedby cutting away its lower end. sothat the bail 41 andassociated roller; 42 may swing rearwardly without, interference fromthe plate-.28: v

' The specific the mechanism. entirely fooltproof and to prevent faultywinding of the awning 'on its roller evenif the tape is. carelesslyhandled or jerked; The flanges of-lthe channel pieces24 and 30retain-thetape 32 against lateral movement int-such. a manner that onlya true torque maybe applied tan- The tape cannot slip sideways with aresultant, drawing oil action or partial longitudinal strain beingimposed on the roller which might, crease or jam the awning.

The bracket fixtures. of the present invention are devoid of springs,gears and delicate mechanis n; which might be injured by careless orstrenuous handling of the manipulating tape, the tape retarding,mechanism which is carried by the inner retarding action on the tape asthe tape is drawn over them in either direction.

It will be seen that there is herein described. a device in'which theseveral features of this invention are embodied and which device in itsaction attains the various objects of the invention and is .well suitedto meet the requirements of practical use.
